IF D Part III [4 marks] a] [2 marks] Suppose you want to estimate the average living area of the real estate properties in the region. If you want to obtain a 95% condence interval with a margin of error of i: 50 square feet, what sample size would you recommend? Assume for this exercise that the population standard deviation is 641 square Feet. h] [2 marks] Assume that you now would like to know what proportion of the real estate properties in the region are ideal for a family of tour. This population proportion is not known. To estimate this population proportion with a margin of error of :I: {1.112, what sample size would you recommend? Consider a 90% condence level
